煤CS2—NMP萃取物丙酮可溶物的GC／MS分析

煤的溶剂萃取物富含多种高附加值聚合材料的单体。依次使用CS2—N御混合溶剂(1：1，V／V)、丙酮对南桐烟煤和云南褐煤进行级分，并对其丙酮萃取物(AS级分)的组成用GC／／MS进行分析。结果表明：丙酮可溶级分中主要含有脂肪烃、芳香族化合物、含氧衍生物和含氮化合物等，其中含氮杂原子化合物以甾类化合物为主，含氧衍生物则主要为酯、酚。2种煤样的AS级分均没有检测到硫、磷杂原子化合物，也没有发现典型的稠环芳香族物质如萘、菲、蒽等的存在。在南桐烟煤的AS级分中，检测到十六烷酸三甲基硅酯、N—丙炔基—N′N′N″N″—四甲基—1，3，5—三嗪三胺两种物质。

GC/MS Analysis of Coal''s CS2-NMP Extract Acetone Soluble Fractions

Components extracted from coals contained a lot of monomers , which can be synthesized into many kinds of important and valuable polymers. Nantong bituminous and Yunnan lignite are extracted with carbon disulfide-N-methyl- 2-pyrrolidinone (CS2-NMP) mixed solvent and Acetone at room temperature in turn. The Acetone soluble fractions are analyzed by GC/MS. Experimental results demonstrate that the Acetone soluble fractions mainly consist of aliphatic hydrocarbons, aromatic hydrocarbons, nitrogen-containing compounds and oxygen-containing derivatives. Nitrogen-containing compounds mainly consist of cholesterin, oxygen-containing derivatives mainly consisted of ester and hydroxybenzene,etc.However, sulfur-containing compounds, phosphorus-containing compounds and polycyclic aromatic compounds can not be detected. Moreover, hexadecanoic acid trimethylsilyl ester and Hexadecanoic acid, trimethylsilyl ester are tested in Nantong coal's Acetone soluble fraction.
